The ARB3D flight computer altimeter utilizes both an
accelerometer and a barometer for optimal performance in an altimeter. The
powerful processor performs real-time floating-point arithmetic for
precise readings of logarithmic altitude. Not only are the acceleration
and barometric values stored, the exact timing between readings are also
recorded. This altimeter embeds a ‘Smart-Polling’ algorithm. This means
during the ascent phase of the flight it is polling at a rate of 30
samples/second and only 10 samples/second during the descent rate until
touchdown has been detected. This is to conserve memory for long duration
flights or for multiple short flights without downloading the flight
data.

The ARB3D has the ability to deploy 3 high current
independent channels: air start/staging with configurable delay, apogee
and low altitude deployment. Both the delay and altitude settings are not
restricted to pre-set values, but to a range of values in increments of
0.1 seconds and 1 foot.

BasicX-24
Chip

Inside the ARB-3D altimeters utilizes
the World's most powerful programmable Microcontroller, the BasicX-24.
This part was choosen because of so many packed features. Some of
the features include multitasking, full IEEE floating point math, 8x 10-bit ADC channels, 32k
of EEPROM, 65,000 instructions per second and much more! This module
can be purchased seperately for any custom
project.
